To all whom, it flea/y coir/eerie;

Be it known that'we, JAooB FISCHER, a citizen o E SwitzerlandflbdHERMANN SCHNEIDER, a citizen of Germany, hothiresiding at Solothurn, Republic ofSwitzerland, have invented certain new and useful lm'provements in Couplings for Wires, Conductors, or the Like; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same. a

This invention has for its object to provide a means for coupling wires or conductors together; and it consists ofrafieizible sleeve of helically-wound wire,"which forms when in a free state the wall of. a'spirally shaped socket of suit-able length, so that when the ends of the sleeve-coil are turned back the ends of the two wires or co nductorsiwhich are to be coupled together can be inserted side by side into the interior of this sleeve-coil, which is now practically straight, and the ends of the spiral then released; I The overlapping ends of the wires or conductors are thus gripped tightly together and heldiby the torsion in the spiral coil.

In the accompanying drawings a form of construction of the object of this invention is shown as an example. 7

Figure 1 is a side elevation, and Fig. 2 an end elevation, of the flexible sleeve in a free state. Figs. 3 and dare side and end elevations, respectively, of a wire-joint made with the aid of the sleeve accordingto'this'invention.

From Figs. 1 and 2 is clearly seen how the continuous wire coils of the sleeve Ct form the Both the ends; I; and 0 may be submitted to great pullingfstrains without either of them slipping in the coil-sleeve a.

Having now particularly described and as certained the natureof our said invention and in what nianner the same'is to be performed, we declare that what we claim is- A wire orco'nductor coupler consisting of a flexible sleeve ,ofhelically-Wound wire the coils of which when in a free state form the walls of a spirally-shaped socket so that when the ends ofQthis sleeve-coil are turned back the ends'of the wires or conductors may be inserted into the interior of this sleeve-coil, the interior of which now forms an approximately straight 'bore, and by releasing the ends of thecoil the ends of the wires or condnctors are gripped and held fast in consequence of the torsion in the sleeve-coil.

In testimony whereof we aflix our signa tures in presence of two witnesses.
